Questions about this pairing

Which panel is better: Phono Solar PS710M13GFH-22/WNH or Phono Solar PS710M13GFH-22/WSHW?
According to our database: Phono Solar PS710M13GFH-22/WSHW tolerates heat better (temp coeff -0.240%/°C vs -0.290%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Phono Solar PS710M13GFH-22/WNH and Phono Solar PS710M13GFH-22/WSHW?
Phono Solar PS710M13GFH-22/WNH has a module efficiency of 22.86%, while Phono Solar PS710M13GFH-22/WSHW is 22.86%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Phono Solar PS710M13GFH-22/WNH use vs Phono Solar PS710M13GFH-22/WSHW?
Phono Solar PS710M13GFH-22/WNH uses TOPCon cells; Phono Solar PS710M13GFH-22/WSHW uses HJT. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.
What is the warranty on Phono Solar PS710M13GFH-22/WNH and Phono Solar PS710M13GFH-22/WSHW?
Phono Solar PS710M13GFH-22/WNH has a 30 years power warranty; Phono Solar PS710M13GFH-22/WSHW has a 30 years power warranty. The power warranty guarantees a minimum percentage of rated output at the end of the warranty period (typically 80-87%). Product (materials) warranties are usually shorter.
Are Phono Solar PS710M13GFH-22/WNH and Phono Solar PS710M13GFH-22/WSHW bifacial panels?
Both Phono Solar PS710M13GFH-22/WNH and Phono Solar PS710M13GFH-22/WSHW are bifacial - they capture reflected light from the ground, which can add 5-15% more annual energy on ground-mount or elevated rooftop installations with a light surface beneath.
